An interagency management team says the Bertschi Road Fire south of Glenwood is nearly 75% contained.  With minimal activity seen on the fire Monday, crews were able to remove remaining areas of heat near the perimeters while increasing levels of containment.  Crews have placed hose lines around the perimeter of the fire and a handheld heat sensing tool is being used to search for heat sources within the containment lines where crews will focus on mopping up.   Eight water tenders are located on site to support hose lines as crews are tasked to achieve 100% mop up along and within the fire perimeter.  In some areas around the perimeter of the fire, up to 300 feet of mop up has been achieved.  The fire started on July 16 and remains under investigation.
